Thus, multicast feeds can travel through unicast routers and be recognized and processed as the multicast packets they really are upon reaching an mrouter" (Savetz). The success of this temporary measure led to a marketing shift away from unicast routers and made multicast routers a PC standard as people began to demand machines that could handle the amount of traffic generated by such real-time multimedia devices.
